WOODEN` VESSEL.

SPECIFICATION forming part of Letters Patent No. 234,752, dated November 28, 1880.

Application filed September 21,1880. (No model.) i

To all whom it may concern.-

Be it known that I, HARVEY K. CARTER, a

citizen of the United States, residing in Camden, New Jersey, have invented an Improve- 5 ment in Wooden Vessels, of which the following is a specification.

The object of my invention is to so seal the plauking ot' a wooden vessel to the ribs as to add to the general security of the vessel, and

1o especially of those which are provided with water-tight bulk-heads.

In the accompanying drawings, Figure l is a transverse section ot' part ot' the hull ot' a vessel showing my improvement; Fig. 2, a

15 sectional plan on the line 1 2, part ofthe planking being removed in this View; and Figs. 3 and 4, views illustrating my invent-ion and drawn to an enlarged scale.

The greater portion of the ribs A of the veszo sel are of the usual character; but at intervals throughout the hull a rib is grooved both on the outer and inner side, and where such arib occurs the inner planking, B, and outer planking, D, are grooved to correspond in shape 25 and locality with the grooves of the ribs. The

spaces thus formed are occupied by tightlyfitting wooden strips. The strip G, Fig. 4, for instance, lits partly in the groove of the inner planking and partly in that in the inner side 3o of the rib, while the strip H tits partly in the groove of the outer pla-liking and partly in that in the outer side of the rib.

The grooves in the ribs should extend throughout their whole length, or at least 3 5 above the hold water-line.

This plan tends to isolate the space between the two plankings on one side of the rib from that on the opposite side, and to render the isolation more complete I prefer, in building the vessel, to bore a hole wherever two 4o planks meet, at the junction of those planks, through the latter and through the strip into the rib, and to drive a pin, a, into the said hole.

Water-tight bulk-heads are sometimes of no 4 5 avail, for the reason that the water, when the outer or inner planking has been more or less shattered and loosened from the ribs, may pass between the two plankings to a compartment separated from that to which water has gained 5o access. This is effectually prevented by my improvement, as will be readily understood by reference to Fig. 3, in which I represents part of a water-tight bulk-head, the sealingribs preventing communication between the 55 spaces w and y. l

It is not essential that the bulk-head should in all cases be built in a position adjoining one of the sealed ribs, and it will be apparent that this mode of sealing the ribs to the 6o planking or plankings of vessels must add to the security of the same in the absence ot' bulk-heads.

I claim as my inventionl. The combination, in a wooden vessel, ot' 6,5 grooved ribs and grooved planking or plankings, with strips adapted to the said grooves, substantially as described.

2. The combination ot' the grooved ribs, grooved planking, and strips, with pins a, sub- 7o stantially as specified.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

HARVEY K. CARTER.
